Two Roads
A small orders service: an Express route, a shared query helper in src/db/orders.ts, a CSV exporter and a nightly digest job. The ticket is one line — paginate GET /orders, 50 per page. Two roads reach it and both of them work. Only one of them sends you a bill, and the bill is turns, rework and peak context.
Nothing here calls a model or touches a repo. The scenario is a state machine, so the same sequence of instructions always ends in the same place — which is what makes the feedback afterwards a fact rather than an opinion. You start 5,280 tokens down before typing a word; that is what a real session costs at launch.
